PDF Extensions stops running my cf-code since version 1.0.0.76

I have a site, where I store my output into a variable, then I output the content of the variable and additionally write the content with cfdocument into a pdf-file. This worked with the PDF-Extension 1.0.0.75.
After update to 1.0.0.76 and 1.0.0.77 it doesn't work anymore.
Lucee stops without any hint. The logfiles don't show an error.

Ciao, Michael (I hope someone understands my gibberish 😉 )
